' COMBINATION-TRUCK.

Application filed August 17, 1918. Serial N0. 250,409.

This invention relates to improvements in truck bodies, andparticularlyto that type attached to motor trucks known as dumpingbodies, the principal object of the invention being to produce such abody in which the sides may be spread out level with the floor for thepurpose of transporting wide and bulky articles such as furniture, heavymachinery, etc., which feature will widen the scope of usefulness ofsuch dumping body trucks, the use of which is at present confined to thehauling of such materials as gravel, rock, loose cement, and the llke.

A further object is the combination with the drop-sides of an end boardwhich may swing out when the body is raised to dump and which isremovable when the sides are dropped, thus leaving a flat platformunobstructed by any vertical members which would limit the size andshape of any article placed thereon.

A third object of the invention is to produce such a body as will beinexpensive of construction and simnle-of operation and which will beextremely eflicient for the purposes for which it is designed.

These objects, I- accomplish by means-of such structure and relatlvearrangement of,

parts as will fully appear by a perusal of the following specificationand claims.

On the drawings, similar characters of reference indicate correspondingparts in the several views.

Figure 1 is a side elevation of my improved body, shown in dumpingposition on the frame of a motor truck.

Fig. 2 is a cross section taken relatively on a line 22 of Fig. 1.

Fig. 3 is an enlarged fragmentary View showing an end board catch andrelease.

Fig. 1 is a fragmentary top view showing the connection between thefront end and side boards.

Referring now. more particularly to the characters of reference on thedrawings, the numeral 1 designates the main frame of the truck, to therear end of which is hinged, as at 2, thebody 3 of the truck. The frameofthe body is .built up in the customary manner of longitudinal beams orstringers 4 to which the endhinges are secured, cross beams 5 extendingover. the beams a, and suitable flooring 6 laid lengthwise on the beams5, :the flooring extending rearward beyond the hinges 2 for a certaindistance to prevent the material being dumped fromfalling on the truckframe.

Mounted to the floor 6 by means of a plu- .rality of hinges are sideboards 8 whose lower edges are normally adjacent the top of the floor,the hinge pins' being one continuous' rod 9 runnin lengthwise of thebody on each side. Secured to the side boards at spaced intervals arerigid vertical supports 10, these supports extending downward below thelevel of the floor and side boards, andbeing, adapted to. bear on theunderside of the. floor when the sides are lowered to retain the sideslevel with the floor.

These supporting members are: bent outwardly as at 11, in order .to passaround the hinge-pin 9'witl1'out bearing against the same.

They are also preferably constructed of channel iron .or similar shapes,in which lightness.

The front end with the usual hydraulicflift 12 whereby the body israised for dumping.

The forward ends of the side boards 8 project over the ends of thefrontend board 14,

which is rigidly mounted to the body 3.

Such forward ends are provided with cleats 8 on either side of the board14: and straddle the same when the side boards are in vertical position.Straps 15 are secured to the side boards on the outside thereof in linewith the rearmost of the cleats 8 and a rod 16 passes through the straps15 and the said rearmost cleats, which rod is provided with hand screws17 At the rear end of the side boards are secured straps 18 projectingabove the top of the side boards. Straps 18 are secured to the rear endboard 19 projecting over the top thereof, such projected ends being bentto form eyes in line with the straps 18.

great strength andrigidity is-combined with Patented Oct. 21, 19 19.

of: the body connected A rod 20 passes through straps 18 and 18 withhand screws 21 thereon, such end board being held solely by the rod 20and adapted to swing on such rod as a pivotal point. The end board 19 isheld normally against the side boards 8 by means of catches 22 on theouter ends of straps 22* mounted under the floor on one of the crossbeams 5, such straps being of spring steel and normally pressing upwardto hold the catches in engagement with the outside of the end board 19.

A rod 23 is turnably mounted to the floor above the straps 22 and haslugs 24: thereon adapted to bear against the straps. This rod has an arm25 downwardly depending therefrom, which arm has a connected rod 26pivot-ally secured thereto running to the forward end of the body andconnected at that point to an operating lever 27 mounted on the body 3.Thus when the lever is pulled, the lugs 24 are pulled down against thestraps 22 which pressure pulls the catches out of engagement with theend 19 and allows the same free movement outwardly.

In the operation of the device, supposing it is desired to use the bodyas a dumping body only, the sides remain in their vertical positionbeing held there by the hinges 7 at the bottom and the rods 16 and 20with the screws 17 and 21 at the top. The rear end board is then free toopen out as the body is raised by the operation of the lever mechanism.h'ereinbcfore described.

Should it be desired, however, to use the body as a fiat platform, thescrews 17 and 21 are removed from their respective rods, the

sides are then lowered to. a horizontal position till they rest on thesupports 10. This, of course, frees the rear end board 19 from anyconnection with the body and the same may be stored or carried on thetruck in any suitable place until such time as it is desired toreassemble the sides of the truck body.

From the foregoing description it will be readily seen that I aveproduced such a device as substantially fulfils the object of theinvention as set forth herein.

Copies 01 this patent may be obtained for While this specification setsforth in detail the present and preferred construction of the device,still in practice such deviations from such detail may be resorted to asdo not form a departure from the spirit of the invention, as defined bythe appended claims.

Having thus described my invention, what I claim as new and useful anddesire to secure by Letters Patent is:

1. In combination with a dumping truck body having a front end boardrigidly mounted to the flooring and side boards hinged to the flooringand adapted to be lowered to the level of the floor and retained in thatosition, demountable means common to both side boards at the upper frontand rear ends thereof whereby the same may be held in a verticalposition, and an end gate hinged along its upper edge to the rear one ofsuch side board holding means, whereby when the body is raised to dumpthe truck the end gate will swing automatically on its hinges, and maybe removed with the side board holding means when desired to lower thesides to form a platform.

2. In combination with a dumping truck body having a front end boardrigidly mounted to the flooring, and side boards hinged to the flooringand adapted to be lowered to the level of the floor and retained in thatposition, demountable rods common to both side boards at the upper frontand rear ends thereof whereby the same may be held in a verticalposition and an end gate hung along its upper edge on the rear one ofsaid rods, whereby when the body is raised to dump the truck, the endgate will automatically swing on the rod, and may be removed with theholding rod when desired to lower the sides to form a platform.

In testimony whereof I aflix my signature in presence of two witnesses.
